  產(chǎn)品介紹
  
  ADAM-6251/ST是一個帶有1個光纖端口的工業(yè)級以太網(wǎng)交換機，可迅速高效地擴展工業(yè)網(wǎng)絡(luò)。ADAM-6521/ST有1個光纖端口和4個RJ-45端口。用戶可采用光纖，以防止噪聲干擾，傳輸距離可達15km。ADAM-6521/ST接線端子支持+10~30VDC，過壓保護電壓為3000VDC，以避免系統(tǒng)被高壓損壞。其工作溫度為-10~65°C（14 ~ 149°F），可在惡劣環(huán)境中工作。通過六個LED指示燈，故障修復(fù)更容易。每個端口有一對指示連接狀態(tài)和傳輸速率的LED指示燈。這樣可以方便地告知用戶任何沖突，連接狀態(tài)變化，電源故障和數(shù)據(jù)接收與否，以便實時在線診斷。
